Does the fan require a round hole? If so what size?

Round hole, approx. 4 1/2". There is a template included. I have 3 of these mounted on the top of my tall plastic storage units. They move air (very lightly and slowly) to keep the condensation away. I mounted another on top of the toilet vent pipe in my travel trailer and it is just enough to pull air and odors out of the tank. I would not mount it in a vehicle for comfort cooling as it really is designed as a yacht harbor "dock box" vent for condensation. It doesn't move enough ari for much else.

I used the 4 I bought with with rectangular under-mount sinks and I do not see why a round one should not work. The rectangular ones are not much more and look more interesting.

Hole pattern and size are the same as 120 mm fan. You can use fan screws to attach it to a 120 mm fan. Distance between holes are 105mm and holes are 5mm.

Yes, the large round fitting you see in the picture is the vent to outside. you need to attach a hose, not included, or a piece of duct work from the fan outlet to an outside area.

Yes. It needs two round holes (about 4-5" diameter) to work for a/c. Only one vent is needed for heater.

I don't believe the installation instruction specify a figure but more space is better for cooling air flow. More space may allow for less usage of the cooling fan.

Use a larger screw. I used a larger screw when my fan wobbled. You should be fine.

the answer if not already answered is it has holes for both in it for multiple fan options

Yes, in fact I strongly suggest you to it regularly to maintain a strong air flow and to extend the life of the fan. The two round vents at the bottom are held on with screws. Just open them, remove any dirt or dander that is clogging the fan, and then screw them back on. The difference it can make is profound.

There are several sizes depending on the year and model of the unit, best way to be sure is to take off the inside part of the ac and measure the hole

This is an UPGRADE kit for an existing fan. However, the fan does fit in a standard 14x14 hole. But if you do not already have a "Fantastic Vent", this won't work for you. You need model 6600R/417, which is the WHOLE thing.

Having just installed one of these, I woul say no. It requires a circular hole through the whe wall of approximately 8 inches.

Any fan that would be first covered up the fan opening by those dimensions. And would have to have center screw as this is how it is mounted. I know some fans are mounted by clips and no center screw. Those you won't be able to use on. Feel free if you have more questions. I actually just mounted on a non Broan brand fan.

Yes it uses a 6 " round vent. You need standard metal venting from a hardware/home store to connect it to your existing exhaust duct. Just attach with a couple of metal screws and seal with foil tape.

Yes it has 4 mounting holes. It's a 4.5" fan so the holes are about a 4" sq

The purpose of the fan is to remove the heat from the enclosed environment by forcing air out which causes cooler air to be drawn in. If you simply place the fan inside of the enclosed area, it will only serve to circulate the warm air and thus never provide any cooling at all. Do not install it without having a hole for the fans to be mounted to as well as an equally sized hole on the opposite side of the enclosure to allow for cooler air to come in. This is a great question to ask though.

not sure. I know it has a 36 mm nut on the fan. I can check the dimensions.
